BOSTON — Bruins goaltender Tuukka Rask today signed a two-year contract extension. The 22-year-old would have been a restricted free agent after the season.

“We liked what we saw in each of the camps. We saw progression in his training camps,” said general manager Peter Chiarelli, who said talks with Rask’s camp opened up during training camp. “We saw progression in the American Hockey League. And it was enough for us to decide to come to a deal.”
